Michigan has had little offensive line depth since Brady Hoke's arrival in 2011. That shouldn't be a problem in future years, as the Wolverines have recruited the position hard in the past two cycles.Melanie Maxwell | AnnArbor.com

Michigan began the day with one of the country's preeminent offensive line recruiting classes for 2013.

It'll end the day even stronger -- and deal a blow to a league rival along the way.

Samuelson is a 6-foot-5, 280-pound native of Plymouth, Ind. He is a three-star prospect and the nation's No. 31 guard according to Rivals, and a four-star player and the No. 25 guard according to Scout.

Michigan has played with dangerously thin offensive line depth the past two seasons, and is expected to start at least two redshirt freshmen next year. But depth appears to be on the way.

After taking four elite offensive linemen in 2012, the Wolverines now have six commitments at the position for 2013, each of whom receive four stars from at least one recruiting site: Kyle Bosch (Wheaton, Ill.), Logan Tuley-Tillman (Peoria, Ill.), David Dawson (Detroit Cass Tech), Chris Fox (Parker, Colo.), Kugler (Wexford, Pa.) and Samuelson.

Another offensive lineman, Scott Sypniewski, is committed as a long snapper.

Michigan has 25 verbal commitments overall for 2013, a class that ranks No. 5 according to Rivals, No. 1 according to Scout and No. 7 according to ESPN.

Six of Michigan's commits -- including Bosch and Tuley-Tillman -- are already on campus as early enrollees. The rest of the prospects can sign letters of intent beginning Feb. 6.
